-There may be more than one LSM that provides IPC data
-for auditing. Change security_ipc_getsecid() to fill in
-a lsmblob structure instead of the u32 secid. The
-audit data structure containing the secid will be updated
-later, so there is a bit of scaffolding here.
+Change the security_task_getsecid_subj() and
+security_task_getsecid_obj() interfaces to fill in
+a lsmblob structure instead of a u32 secid in support of
+LSM stacking. Audit interfaces will need to collect all
+possible secids for possible reporting.
